Abstract

L'invention concerne un dispositif de récupération d'énergie comprenant un redresseur de fréquence inverse conçu pour recevoir une énergie mécanique à une première fréquence, ainsi qu'un transducteur électromécanique à semi-conducteurs couplé au redresseur de fréquence inverse, conçu pour recevoir une force fournie par le redresseur de fréquence inverse. Cette force, lorsqu'elle est fournie par le redresseur de fréquence inverse, permet de soumettre le transducteur à semi-conducteurs à une seconde fréquence, supérieure à la première fréquence, et, ainsi, de générer de l'énergie électrique.
